A conjectured upper bound on the Choptuik critical exponents
Nuclear Physics B, 2021 Near-critical type II gravitational collapse is characterized by the formation of arbitrarily small black holes whose horizon radii are described by the simple scaling law rBH∝(p−p⁎)γ, where γ is the matter-dependent Choptuik critical exponent and Δp≡p−p⁎

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Investigation of critical slowing down in a bistable S-SEED
, 2003 A simulation of S-SEED switching based upon experimental data is developed that includes the effect of critical slowing down. The simulation's accuracy is demonstrated by close agreement with the results from experimental S-SEED switching. The simulation

THE CRITICAL EXPONENT θ′ IN SPIN GLASSES [PDF]
Modern Physics Letters B, 1999 Short-time dynamic scaling behavior of the 3D ± J Ising spin glass is studied by Monte Carlo methods. Starting the replicas with independent initial configurations with a small pseudo-magnetization, the dynamic evolution of the overlap q(t) between two replicas is measured.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

The Critical Exponent of Nuclear Fragmentation
Acta Physica Hungarica A) Heavy Ion Physics, 2003 Nuclei colliding at energies in the MeV’s break into fragments in a process that resembles a liquid-to-gas phase transition of the excited nuclear matter. If this is the case, phase changes occurring near the critical point should yield a “droplet” mass distribution of the form ≈A −T, with T (a critical exponent universal to ...

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Critical exponents of the modified F model [PDF]
, 2020 It has been argued (Kadanoff and Wegner 1971) that the existence of continuously variable critical exponents x and x' We consider here a special case of the eight-vertex model and report the result on its exponents and the verification of the ...
